On the Laplacian subalgebra of certain tensors of group von Neumann algebras
Teodor Stefan Bildea
In this paper, we exhibit strongly singular maximal abelian subalgebras living inside certain k-folded tensors of von Neumann group factors. The two classes of groups under conside…

Triangle Joins of SP1 Equivalence Relations and their Cost
Teodor Stefan Bildea
Free joins of measure preserving equivalence relations, with or without amalgamation were introduced by Gaboriau, who studied their cost and obtained a formula for the cost of free…

The Laplacian subalgebra of the k-folded tensor product of the free group factor with itself is a strongly singular masa
Teodor Stefan Bildea
In this paper, we present a new class of strongly singular maximal abelian subalgebras living inside the k-folded tensor product of the free group factor (on N>1 generators). A. Si…
